I used Serviio for a long time. Before a week ago, I usually use Serviio to watch iTunes movies on my Samsung TV after removing the DRM. I know all the iTunes movies are DRM-ed but personal viewing is usually fine. What I used is the free tool Requiem. However, now it crashes on my computer, which runs Windows 10 and 64 bits. So is there any other methods to play iTunes movies on Samsung with Serviio?

As you note, you can't play an iTunes movie without removing the DRM. If Requiem is no longer working on your computer, I would first contact them to see if they have a new version for Win 10. Beyond that, this isn't the place to discuss removing DRM from your media. Not certain if the Serviio forum rules forbid discussing it, but many do. As far as other potential products, a web search would most likely turn up any alternatives.

There may be two solutions for you to fix this issue:the first one is to contact the free tool requiem team asking if they can fix this problem. if you are able to refine that software then you will be able to use the free tool requiem again.in case of your free tool requiem can't be fixed, I think if you still want to remove the DRM from iTunes movies and TV shows, you will have to choose another DRM removal. Actually you have lots of options on the internet, and some of them are pretty good. I also use DRM removal to remove it from iTunes movies. The one I am using is TuneFab iTunes M4V Converter. it is a pretty good one supporting removing DRM from iTunes M4V videos and convert them into MP4, after converting the M4V into MP4, I can transfer them into any other non-Apple devices for free playback. If you are converned about the quality loss, no need to worry, the conversion is lossless. Maybe you can download the trial version to have a try.

To play iTunes movies on Samsung devices, my option is to use DRM removal software-DRM Media Converter. It is a program for us to convert DRM protected iTunes movies to non-DRM protected iTunes movies. It works at 30x faster speed to convert all videos losslessly. After conversion, you can play all iTunes videos on any devices without limitation. You can check more details about it on here. Hope this point is useful to you.
